Specification of Letters Patent.

Patented Oct. 27, 1914.

Application filed October 9, 1911. Serial No. 653,702.

T0 all 'whom may] concern Be it known that l, WILLIAM F. Kermt, acitizen ot the United States, residing at Dayton, in the county ofMontgomery and State of Chio7 have invented certain new and usefulimprovements in Resilient lV heels; and l do declare the following to bea full, clear-,and exact description oi the invention, such as willenable others skilled in the art to which it appel-taies to make and usethe same, reference being had to the accompanying drawings, and to theletters and `figures ot reference marked thereon, which iorm a partoil'v this specification.

rlhis invention relates to new and useful improvements in resilientwheels for motor vehicles. t

The object et the invention is to provide a wheel oit the above typewith structural features constructed and arranged as set forth in thedescription to follow, and as pointed out, in the subjoincd claim. y

Referring to the accompanying drawings, Figure 1 is a side elevation ofmy improved resilient wheel; and Fig. 2 is a section on the line a-a ot'Fig. 1.

Particularly describing` the same, the wheel consists of a hub 1provided with apertured ears `.2 which receive pintles t.`

Pivoted on the pintles 4: are the inner female members 3 et telescopicspokes. The ears 2 are separated a sufficient extent to 'form broad andsubstantial `bearings for the spokes, which bearings are capable ofresisting the side thrusts received by the wheel. The female members 3receive outer male members 5 of telescopic spokes, provided withapertures which receive pintles 7. The pintles 7 pass through thebisected apertured portions `6 which are integral with the annularflange 11 extending from the inner side et the wheel rim 12. By thusconstructing the rim, the same is made of a minimum amount `ot materialyet is of considerable strength. The pintles 7 are supported at each endby a broad bearing. The bearing for the male members 5 therefore of thespokes are ot a sutlicient width te overcome the bending and twistingstrains thrown upon the rim when the wheel reeeives a lateral thrust.The connection between the hub 1 and the rim 12 through the telescopicspokes is a free sliding one which permits the hub to move relatively tothe rim. This movement is controlled by a plurality of resilient membersor springs 10 which lie at equal distances between thetele' scopicspokes. The inner ends et the springs l0 are connected to apertured lugs8 eX- tending from the hub, while the outer ends oi. said springs arereceived by openings; 9 in the inner flange 11 of the rim.

llt will be seen that a resilient wheel as thus constructed, is oi lightweight and yet is oi sulicient strength to overcome lateral strainsthrown upon the rim. By this arrangement, the springs and spokes do notinterfere. with each other and may be designed independently therebyallowing the parts to be proportioned according to their requisitestrength, and as they all lie in the same plane they are adapted toreceive the thrusts and strains without a tendency to distort the hub orthe rim of the wheel.

I claim,

A wheel of the character specified, comprising a rim having an inwardlyprojected annular flange, said flange having uniformly positionedbisected portions, a hub having alincd` apertured ears projectingthere-trom and lying substantial distances apart, a series et telescopicspokes, the tubular members ot said spokes having each a wide base whichis pivotally connected bctween the apertured ears ot the hub, the outermembers of said telescopic spokes be ing pivotally mounted between thebisected portions oi the rimflange in alinement with the transverse axisoit the hub, and a series of helical springs arranged at uniformdistances between the spokes and in alinement therewith and with thetransverse axis of the hub, said springs having their inner endsconnected to apertured ears on the hub midway between the ears te whichthe tubular member ot' the spokes are connected and the outer ends ofsaid springs being connected with the rim flange, substantially asspecified. i

In testimony whereof I aliix my signature, in presence of two witnesses.
